Background: Carotid cavernous fistulas (CCF) often present with diplopia secondary to cranial nerve palsy (CNP). Immediate development of postoperative CNP has been described in the literature. This study described delayed-onset of CNP after complete and reconfirmed obliteration of the CCF and resolution of initial CNP. Methods: A retrospective analysis was performed on patients with indirect CCF between 1987 and 2006 at 4 academic endovascular centers. Details of the endovascular procedures,...

Abstract: Vision problems from giant cell arteritis (GCA) can be difficult to diagnose as patients may present with vision loss in the absence of systemic symptoms, have other comorbidities that affect inflammatory blood markers, or have other ocular diagnoses. We present 3 cases illustrating this point including a patient with advanced glaucoma with worsening vision from posterior ischemic optic neuropathy from GCA, a patient with arteritic anterior ischemic optic neuropathy (AAION) erroneously...

Objective: To evaluate the ability of macular ganglion cell and inner plexiform layer (mGCIPL) and retinal nerve fiber layer (RNFL) thickness measurements by long-wavelength swept-source optical coherence tomography (SS-OCT) to assess retinal ganglion cell (RGC) damage in nonarteritic anterior ischemic optic neuropathy (NAION). Methods: A retrospective study of 20 patients with unilateral NAION was performed. SS-OCT scanning of the macular and peripapillary areas was performed to measure...

Background: Visual acuity has been a significant outcome measure in clinical trials for patients suffering from neuro-ophthalmological diseases and multiple sclerosis; however, there are limited data on the comparison of various testing strategies in pediatric patients with these disorders. Clinical trials using vision as an outcome could include a variety of tools to assess the acuity, including 2-m and 4-m standardized retroilluminated charts. Methods: We investigated the difference...

Abstract: A 70-year-old woman presented with acute awareness of decreased color vision in her right eye. Fundus examination and a flash electroretinography (ERG) were both normal. A multifocal ERG (mfERG) however revealed foveal depression, and thinning of inner nuclear layer was noted on macular optical coherence tomography (OCT), and a diagnosis of resolved paracentral acute middle maculopathy was made. Clinicians should be aware of the complementary role of OCT and mfERG in unexplained acute...

Abstract: A 51-year-old man presented to the ophthalmology service with binocular diplopia and facial numbness. The patient was returning from a trip to Mexico. He reported having been hit in the left periocular region by a fish while swimming. Local doctors repaired a laceration in the left lateral canthus shortly after the incident. Orbital imaging revealed 2 needle-like foreign bodies corresponding to retained pieces of a needlefish jaw in the left orbit. Given the location of the foreign...

Abstract: Hemorrhagic lateral geniculate nucleus (LGN) insults are rare but have been reported in association with tumors, vascular malformations, and trauma. The localization of LGN lesions is facilitated by recognition of pathognomonic visual field defects. A 21-year old woman developed a sudden onset painless left homonymous horizontal sectoranopia. Magnetic resonance imaging revealed a hemorrhagic cavernous malformation of the right temporal lobe. Optical coherence tomography (OCT) and Humphrey...

Background: Occurrence of comitant ocular deviation in myasthenia gravis (MG) is not well described. Methods: A retrospective analysis of patients with ocular or generalized MG evaluated at a neuro-ophthalmology clinic for a 6-year period. Comitant ocular deviation was defined as magnitude of deviations in all planes varying by

Background: Ophthalmic involvement in acute leukemia is common, with 36% of patients having ophthalmic involvement at the time of diagnosis. However, neuro-ophthalmic involvement is relatively rare. We present a characterization of neuro-ophthalmic findings in patients with acute leukemia and discuss the implications of these findings on patient management and prognosis. Methods: We performed a retrospective review of cases of acute leukemia with central nervous system (CNS) involvement...

Background: Giant cell arteritis (GCA) is the most common systemic vasculitis in the American population older than 50 years and is a sight-threatening and life-threatening disease. It is definitively diagnosed with a temporal artery biopsy. Although there are many studies focusing on the clinical presentation and laboratory values in diagnosing GCA in the general population, studies focusing on the veteran population are lacking. This is the first study describing the diagnostic features of...

Background: Anti-acetylcholine receptor antibody (AChR–Abs) testing is a safe and simple ancillary method for confirming the diagnosis of myasthenia gravis. Despite the test's high sensitivity (85%–90%) for generalized myasthenia gravis, AChR–Abs testing has been reported to have a low sensitivity 44%–66% for ocular myasthenia gravis (OMG). The aim of the study is to assess the effectiveness of AChR binding Abs testing for diagnosing OMG by evaluating the test's sensitivity, specificity, positive...

Background: Given the widely distributed network of midbrain, pontine, cerebellar, and cortical areas involved in the neural control of vergence, one might expect various vergence deficits in stroke patients. In this article, we investigated the localizing value of bedside vergence testing with respect to different supratentorial and infratentorial infarction locations. Methods: Three hundred five stroke patients and 50 age-matched controls were examined prospectively by means of bedside...

Background: Dorsal midbrain syndrome (DMS) consists of a constellation of clinical features, including reduced upgaze, pupillary light-near dissociation, lid retraction, convergence retraction, and eye misalignment. This syndrome results mostly from intrinsic or extrinsic mesodiencephalic tumors or strokes, obstructive hydrocephalus, failure of cerebrospinal fluid shunting to correct obstructive hydrocephalus, and head trauma. Published reports that include imaging corroboration are based on...
